  • a vinyl curtain 70 substantially of a same dimension as the height from the floor surface 26 of the container 1 to the system ceiling 50 is attached to the end on the side of the cooling area 2 of the system ceiling 50 , by which the space is closed.
  • the curtain can adopt a short shop-curtain-like form, so that it will not interfere with the movement of operators while preventing convection of air.
  • the cooling air sent out from the vent 31 a of the indoor unit 31 can be introduced through a path shown by arrow Fc (shown by solid line) with the cooling area 2 functioning as the duct, so that the cooling air can be flown toward the IT equipments installed on the racks without fail, and further, the air containing exhaust heat can be introduced along the path shown by arrow Fh (shown by dotted line) to the intake opening 31 b of the indoor unit 31 . Furthermore, this configuration enables to prevent air containing exhaust heat from flowing into the cooling area 2 , so that the enhancement of cooling efficiency can be realized.
  • a vinyl curtain has been hung on the upper portion of the rack 40 , but the present invention is not restricted to such configuration, and any configuration can be adopted as long as the flowing of air from the heat exhaust area 3 to the cooling area 2 at the upper portion of the rack 40 is prevented, so that the clearance on the upper portion of the rack 40 can be closed by a plate-like member, for example.
